1. General1.1 Introduction

1.1.1 The primary objective of external coatings onsubmarine pipelines is corrosion control. In addition, thecoating system can be designed to provide mechanical protec-tion during installation and operation, and/or thermal insula-tion. A corrosion protective coating may also be combinedwith a concrete weight coating for anti-buoyancy and/ormechanical protection during operation.

1.1.2 Coating applied in a factory to individual pipe lengths isoften referred to as “linepipe coating” (or “factory coating”),see DNV-RP-F106. In this document, “parent coating” issometimes used synonymous with linepipe coating. In order tofacilitate girth welding, areas at each end of the individual pipelength are left uncoated. These areas are normally coated afterwelding, by applying a “field joint coating” (FJC) system. Thesame term applies for coating applied on the welded jointbetween a pipe and a pipeline component (e.g. bend or valvebody) with pre-fabricated coating. In this document, the term“FJC” is used irrespectively of the coating being applied in afactory or in the “field”.

1.1.3 Depending on the type of linepipe coating, the FJC mayconsist of one or more layers of coating materials, for the pur-pose of corrosion control, mechanical protection and/or ther-mal insulation. FJC systems may also be designed to provide asmooth transition to a concrete weight coating of the linepipe,or to a thick-layer thermally insulating coating. This istypically achieved by application of a moulding compound,referred to as “infill”. In some cases, pre-fabricated half shellsare installed by strapping to the field joint.

Guidance note:For certain FJC systems developed for thermally insulated line-pipe coating, the moulding compound serving as an “infill” isconsidered as an integrated part of the FJC.

1.1.4 Linepipe coating may suffer damage during handling,transportation or pipeline fabrication/installation requiringrepairs. This is referred to as “coating field repairs” (CFR). As forFJC, CFR systems may consist of one or more layers of coatingand may be applied in a factory or in the field. Repair of linepipecoating may also apply in the case of deliberate modificationsaffecting the coating, e.g. for the purpose of installation of cablesfor electrical connection between galvanic anodes and pipe mate-rial. Certain FJC systems are applicable also for repair of largesize damage to linepipe coating. (Repair of linepipe coating per-formed by the manufacturer at his premises is not referred to asCFR and is covered in DNV-RP-F106).

Guidance note:In its widest sense, the term “pipeline coating” includes linepipecoating, field joint coating (FJC) and coating field repair (CFR).FJC and CFR are typically carried out by the same subcontractorto installation contractor, whilst linepipe coating is mostly car-ried out by some other subcontractor, contracted by either pipe-line operator, installation contractor or linepipe manufacturer.


1.1.5 Submarine pipelines are almost invariably designedwith a cathodic protection (CP) system, mostly based ongalvanic (or “sacrificial”) anodes. The CP system serves as aback-up for any defficiencies of the pipeline coating, includingdefects during manufacturing and damage during transporta-tion/installation, in addition to any assumed degradation ofcoating materials and mechanical damage during operation.Hence, CP design for submarine pipelines is closely related tothe design and quality control of pipeline coatings, includingFJC and CFR (see 1.5.3).

1.2 Scope

1.2.1 This “Recommended Practice” (RP) has been preparedto facilitate the work of pipeline operators, general contractorsas well as sub-contractors carrying out coating work. While therequirements and recommendations are general, the documentcontains advice on how amendments can be made to includeproject specific requirements, and requirements and/or guide-lines by a regulating authority, or to reflect the pipeline opera-tor’s general philosophy on pipeline corrosion control.

1.2.2 This RP covers the process of applying specific types ofFJC / CFR and ‘infill’ systems. The conceptual and detaileddesign of such systems (i.e. for the purpose of corrosion and/ormechanical protection and thermal insulation), and the verifi-cation of such design by special testing, are not covered.

Guidance note:Pipeline operators and main contractors should consider theneeds to carry out qualification of generic coating systems forspecially demanding applications; e.g. resistance to bending dur-ing installation by reeling and long term (>10,000 hrs) thermaldegradation of critical coating properties associated with highoperating temperatures. Purchasers of linepipe coating shouldfurther consider pre-qualification of coating manufacturers priorto the issue of purchase documents.


1.2.3 The following 9 categories of FJC / CFR systems, appli-cable to corrosion control of submarine pipelines, and includ-ing associated risers, are covered in this document (seeANNEX 1):

— 1A Adhesive tape (PVC or PE backing), with typicalthickness of about 2 mm and mastic type adhesive, appliedon substrate mechanically treated to Sa 2½ or St 3 (FJConly).

— 1B Heat shrink sleeve (PE backing) with mastic typeadhesive applied on substrate mechanically treated to Sa2½ or St 3 (FJC only).

— 2A PE heat shrink sleeve or repair patch (thickness 2-3mm) with modified PE adhesive, applied on top of LElayer (min. 100 mm). Steel substrate treated by blast clean-ing to Sa 2½ .

— 2B As for 2A, but with heat shrink sleeve or repair patchin PP.

— 3A FBE layer (min. 350 mm). Steel substrate treated to Sa 2½. LE (min. 100 mm) for repairs.

— 3B As for 3A (lower FBE thickness may apply), with PEheat shrink sleeve (2-3 mm) applied on top and an interme-diate layer of PE adhesive. (FJC only).

— 3C As for 3A (lower FBE thickness may apply), with PPheat shrink sleeve (2-3 mm) applied on top. Fused bondingof PP to PP parent coating.

— 3D As for 3A (lower FBE thickness may apply), with PP(3mm) applied by flame spraying, wrapping or extrusion(e.g. injection moulding). Fused bonding of PP to PPparent coating.

— 4A Polychloroprene sleeve, wrapping or patch (on top ofprimer) with vulcanised bonding to parent coating. Steelsubstrate treated by blast cleaning to Sa 2½ ( Used for line-pipe coating in the same material type and typicallyapplied by the same contractor).

1.2.4 For concrete coated pipes and thermally insulated pipes,the FJC systems above may be used in combination with amoulding infill. The following 4 types of infill are covered (seeANNEX 2):

i) asphalt mastic ii) polyurethaneiii) rapid setting concrete iv) polypropylene.

DET NORSKE VERITAS

Recommended Practice DNV-RP-F102, October 2003 Amended April 2006 see note on front cover

I and II may be applied directly on the field joint (FJ) with orwithout a primer coat (bonding agent). I, II and III are applica-ble for pipelines with concrete coating whilst II an IV are usedfor PP multilayer coatings for thermal insulation, typicallywith an inner 3-layer PP coating. II and IV may be applied asa homogenous solid product, sometimes with a filler materialadded, or as a foamed product. The manufacturing of halfshells (typically on PU or PP basis) to be strapped around a FJ(with or without a FJC system) is not covered by this RP.

1.2.5 This RP may be fully or partly applicable to similar coat-ing and infill systems, or to FJC / CFR associated with onshorepipelines. The user shall consider the needs for amendmentsand deviations for such applications.

1.2.6 The following activities associated with FJC / CFR arenot covered:

— Requirements for the qualification of supplier specificcoating materials for general (i.e. not project specific) pur-poses (see Guidance Note to 1.2.2).

— Detailed design of FJC for project specific purposes (e.g.heat insulation, see 1.2.2).

— Inspection of linepipe coating during installation and char-acterisation of damage for subsequent CFR. (In case ofminor coating damage; i.e. where the inner corrosion pro-tective coating is not affected, the requirements to CFR inthis document may not be relevant).

— Repair of concrete weight coating.

1.2.7 Although considerations of safety and environmentalhazards associated with coating work and properties of as-applied coating materials (i.e. as reflected by national andmulti-national regulations) are of great importance, such arenever-the-less beyond the scope of this RP.

1.3 Application and use

1.3.1 This (RP) has two major objectives; it may either beused as a guideline for the preparation of manufacturing spec-ifications for FJC / CFR and infill systems as defined in 1.2.3above, or it may be used as an attachment to an inquiry or pur-chase order specification for such systems. If Purchaser haschosen to refer to this RP in a ‘purchase document’ (see defi-nition in Sec. 3), then Contractor shall consider all require-ments in this document as mandatory (see Sec. 3), unlesssuperseded by amendments and deviations in the specific con-tract (see 1.3.4 – 1.3.5).

1.3.2 If reference is made to this RP in a purchase document,the following additional information and requirements shallalways be specified (see Section 3), if applicable and relevantto the specific coating system as defined in the CFR / FJC andInfill Data Sheets of ANNEX 1 and 2, respectively:Information:

(see 5.4.2).

— Project specific requirements to ‘pre-production qualifica-tion testing’ (PQT), including schedule for notificationand reporting, number of FJC / CFR (and ‘infills’ if appli-cable) for testing, and any requirement for qualification ofcoating applicators (see 5.2.2).

— Methods and acceptance criteria for any testing indicatedas “to be agreed” in the applicable FJC / FCR and infilldata sheet of ANNEX 1 and ANNEX 2, respectively (see5.3.3).

— Permissible repairs for FJC, and infill if applicable (see5.9).

— Requirements for marking and pipe tracking, if applicable(see 5.10.1).

— Requirements for documentation, e.g. schedule for supplyof documentation and documentation format. (see 5.10.1).

1.3.3 If inspection and repair of linepipe coating damage onpipe joints as received by Contractor is included in the scopeof work (see 5.5.1), the following requirements shall beenclosed:

— Requirements for inspection for linepipe coating damage;e.g. type or method and extent of inspection and accept-ance criteria.

— Acceptance criteria for linepipe coating repair; e.g. maxi-mum size and number of specific types of defects per pipefor damage considered repairable.

1.3.4 The following items, intended as a check-list, may beincluded in purchase documents, as applicable and relevant.(For specification of amendments and deviations in purchasedocuments, see 1.3.5 below.):

— Additional testing (i.e. requested by Purchaser) indicated“by agreement” in the FJC / CFR or infill data sheet (see5.3.3), and any special conditions for testing (e.g. test tem-perature above or below normal ambient temperature,unless stated in the applicable data sheet).

— Specific coating materials to be used (e.g. supplier specificsystems/grades, see 5.4.3.)

— Specific requirements for automatic control of applicationparameters, e.g. powder application (see 5.7.5).

— Specific requirements for the ITP (5.3.2).— Qualification of personnel for FJC / CFR and ‘infill’ appli-

cation (e.g. during PQT, see 5.2.1). — Specification of management of concession requests

(5.7.1) and non-conformities (5.8.7).— Facilities needed for Purchaser’s quality surveillance.— Regulatory or Contractor’s requirements for control of

health and environment hazards associated with coatingwork.

— Special requirements to handling, storage and transporta-tion of coated pipes, if relevant (see 5.11).

— Further deviations or amendments to this document.

1.3.5 As far as practical, tentative test methods and acceptancecriteria for testing indicated in the ‘FJC/CFR data sheet’ as “tobe agreed” (see 1.3.2) or “by agreement” (see 1.3.4), shall bespecified by Purchaser in the inquiry. Purchaser may also spec-ify any preference for a specic test methods in case more thanone method is specified for mandatory testing (“to beincluded”). If alternative methods are given in the FJC / CFRor ‘infill data sheet’, and no specific method has been specifiedby Purchaser, the method to be used is then optional to Con-tractor.

1.3.6 ANNEX 3, Table 1 and 2 show how deviations andamendments to the common requirements in Sec 5, and to aspecific FJC/CFR or ‘infill data sheet’, respectively, may bespecified in a purchase document.

1.4 Structure of document

1.4.1 Requirements that apply to all categories of FJC / CFRand ‘infill systems’ are given in Sec. 5, whilst those applicableto a specific system are contained in individual FJC / CFR andinfill ‘data sheets’ in ANNEX 1 and ANNEX 2, respectively.

1.5 Relation to DNV-OS-F101 and other DNV docu-ments on pipeline corrosion control

1.5.1 DNV-OS-F101 “Submarine Pipeline Systems”, Sec.8,gives some guidelines to the selection and design of pipelineexternal corrosion protective coatings (including field jointcoatings and concrete coatings), and general requirements totheir manufacturing.

1.5.2 DNV-RP-F106 “Factory Applied External PipelineCoatings for External Corrosion Control” provides detailedrequirements for the manufacturing of linepipe (“factory”)coatings.

1.5.3 Cathodic protection (CP) of coated submarine pipelinesis covered in DNV-RP-F103 “Cathodic Protection of Subma-rine Pipelines by Galvanic Anodes”.

Guidance note:This document offers CP design parameters that are based on therequirements to pipeline coatings in DNV-RP-F106 and in DNV-RP-F103, reducing the need for arbritary conservatism in CPdesign due to potential defficiencies associated with pipelinecoating design and/or quality control of coating maufacturing .

3. Terminology and Definitions

For definition of coating terms associated with submarinepipeline systems, reference is made to 1.1 above.

4. Abbreviations

5. Common Requirements5.1 Coating manufacturing procedure

5.1.1 All work associated with the application of FJC / CFRand any ‘infill’ (including qualification of the application;“PQT”, see 5.2) shall be described in a ‘manufacturing proce-

dure specification’ (MPS). This MPS shall be submitted toPurchaser prior to the PQT and/or start of production.

5.1.2 The MPS shall as a minimum include the following datasheets, drawings, procedures and other information:

— detailed design of FJC (if included in scope of work),defining e.g. parent coating overlap, length and chamferangle of parent coating cut-back, thickness of individuallayers, calculations of heat insulation, design of permanentmoulds or straps for infill, as applicable

— coating material properties, including supplier’s productdata sheets (PDS) and/or certificates (5.4.3 – 5.4.8)

— receipt, handling and storage of materials for surface prep-aration and coating (5.4.9 – 5.4.12)

— preparation of steel surface and parent coating cutback (5.6) — coating application (including control of essential process

parameters, see 5.7)— inspection and testing (5.5, 5.6 and 5.8) — repair of imperfect coating work (FJC / CFR and ‘infill’, if

applicable, see 5.9)— stripping of rejected FJC ( and ‘infill’, if applicable), see 5.9— handling, storage and transportation of coated pipes (if

included in scope of work, see 5.11)— documentation, and marking of FJC (if applicable).

The FJC design documentation and procedures for the last 4items are subject to acceptance by Purchaser. Some detailedrequirements to items for inclusion in the coating manufactur-ing specification are given in 5.4 – 5.11.

Guidance note:For “accepted”/ “acceptance” and “agreed” /”agreement”, seedefinitions in Sec.3.


5.1.3 Purchaser may require that procedures for testing andinspection, handling of non-conformances and concessionrequests and/or other additional detailed information isincluded in the MPS (see 1.3.4).

5.2 Pre-production qualification testing (PQT)

5.2.1 The primary objective of the ‘pre-production qualifica-tion testing’ (PQT) is to verify that the MPS is adequate toachieve the specified as-applied coating properties. Purchasermay further specify that coating applicators are individuallyqualified during the PQT so that their capability to achievespecified coating properties can be verified (see 5.2.2).

Guidance note:The verification of coating properties by destructive testing, asconducted during regular production of linepipe coating (e.g. bypeel testing at pipe ends) is not feasible, or at least cumbrous forFJC. The qualification of a MPS for FJC / CFR and infill isconsequently regarded as crucial. Moreover, the quality of theapplied coating is more dependent on coating applicator skills. Itis therefore recommended that the requirement to a PQT in thisdocument is not waived, that coating applicators are qualifiedindividually during the PQT and that the PQT is witnessed by acompetent person representing Purchaser.


5.2.2 Specific requirements for ‘pre-production qualificationtesting’, including e.g. schedule for notification and reporting,qualification of coating applicators, any preparations of FJC /CFR additional to the minimum requirements in 5.2.5, shall bespecified in purchase documents (see 1.3.2).

5.2.3 A MPS and an ‘inspection and test plan’ (ITP, see 5.3)specific for the PQT, together with a detailed schedule forcoating application, inspection and/or testing, and reportingshall be submitted to Purchaser in a timely manner (as per pur-chase document) prior to start-up of the qualification activities.

5.2.4 Coating application temperature, drying or curing condi-tions shall be according to coating material supplier’s recom-mendations. Data sheets and calibration certificates forinstruments essential to quality control (e.g. temperature sen-sors) shall be available for Purchaser’s review during the PQT.

Guidance note:For FJC application using induction heating for curing of aninnermost epoxy layer, it is recommended that the capability ofeach coil to achieve uniform heat distribution for the period ofcuring is verified by actual temperature recordings during thePQT. The capability of equipment for automatic spraying ofpowder coating to obtain the specified thickness range shouldalso be verified. Moreover, the maximum time between interrup-tion of heating and completion of powder application to achievespecified properties of the coating, should be established.


5.2.5 Coated pipes of the same supply as to be used for instal-lation shall be utilised for the PQT. However, for FJC a simu-lated girth weld may be used for the PQT, except if a full scalebending test according to 5.2.12 is to be carried out. Thenumber of personnel involved in coating application during thePQT, including any supervisor, shall be the same as that usedfor normal production. The duration of the individual mainactivities (e.g. blast cleaning, coating application) shall beroughly the same as to be used during production, and shall bereported.

5.2.6 As a minimum, 3 (simulated) FJs shall be coated with afull coating system. For 3- and multi-layer systems with aninnermost layer of FBE, minimum one pipe shall be coatedwithout adhesive to allow easy stripping of the outer PE / PPlayer for verification of FBE thickness, curing of FBE and PE/ PP ‘as-applied’ tensile properties. For qualification of CFRs,minimum 3 repairs shall be performed (for each repair proce-dure) using the maximum allowable repair size.

5.2.7 FJCs associated with joining of pipes or pipeline compo-nents with different coating systems shall be subject to a spe-cific PQT.

5.2.8 For FJC or CFR to cover welded or brazed connectionsof galvanic anodes or other items, testing methods and accept-ance criteria for verification of relevant properties shall beagreed based on e.g. Purchaser’s tentative specification ininquiry, or Contractor’s proposal.

Guidance note:Testing methods and acceptance criteria will be dependent on thedetailed design that may not be completed at the issue of inquiry.


5.2.9 As far as is practical, qualification of offshore FJC and‘infill’ application shall utilise the same equipment and tools ason the actual vessel. Climatic effects for offshore applicationsshall be taken into account when defining the conditions for afactory PQT. Any significant differences in equipment andtools to be used for PQT and production shall be highlighted inthe MPS for the PQT.

5.2.10 The PQT shall demonstrate that the materials andapplication procedure used for FJC / FCR and any ‘infill’ donot deteriorate the properties of the adjacent linepipe coating(e.g. mechanical properties and adhesion to steel substrate) orany internal pipe coating. It shall further be demonstrated thatproper adhesion is obtained at the overlap to parent coating.Testing methods and acceptance criteria for verification of rel-evant properties shall be agreed based on e.g. Purchaser’s ten-tative specification in inquiry or Contractor’s proposal.

Guidance note:Testing methods and acceptance criteria will be dependent on thedetailed design that may not be completed at the time of inquiryissue. For the parent coating, the verification may include e.g.

testing of resistance to peeling and cathodic disbonding. Verifi-cation of no detrimental effects on any internal coating shouldinclude e.g. visual examination for discolouration, cracking orblistering and adhesion test.


5.2.11 It shall further be demonstrated during the PQT that theapplied FJC (including any ‘infill’) can be efficiently cooled(or cured, if applicable) within the period of time required toavoid damage by downstream rollers or other equipment.

5.2.12 Any need to carry out a full scale bending test to verifyFJC adhesion to parent coating and general flexibility of a FJC/ ‘infill’ assembly should be considered for inclusion in thePQT. Testing may include e.g. visual examination of evidencefor cracking, or disbonding of innermost layer or betweenindividual layers, testing of residual adhesion strength. Theneed for a full scale impact test (simulating trawl board impact)should also be considered. (Any full scale testing shall be spec-ified in purchase documents).

5.2.13 A procedure for stripping of rejected FJC and ‘infill’,and repair of imperfect coating work, shall be qualified duringthe PQT (see 5.9)

5.2.14 Results from all inspection, testing and calibrationsduring qualification, essential operational parameters for coat-ing, duration of individual main activities and coating materialcertificates shall be compiled in a PQT report. Unless other-wise agreed, the report shall be accepted by Purchaser prior tostart of production.

5.3 Quality control of production

5.3.1 Prior to start-up of regular production, Contractor shallsubmit the following documents to Purchaser for acceptance:

— a project specific MPS updated to reflect the processparameters used during the completed PQT

— a project specific ‘inspection and testing plan’ (ITP) forproduction (see 5.3.2)

— a ‘daily log’ format (see 5.7.4)— a description of responsibilities of personnel involved in

quality control.

5.3.2 The ITP shall meet the general requirements of ISO10005, Sec.5.10. It shall be in tabular form, defining all qualitycontrol activities associated with receipt of coating materials,surface preparation, coating application and inspection/testingof the applied coating. The activities shall be listed in conseq-utive order, with each activity assigned a unique number andwith reference to the applicable codes, standards and Contrac-tor’s procedures or work instructions that shall apply for thespecific project. Furthermore, frequency and/or extent ofinspection and testing, acceptance criteria and actions in thecase of non-conformances (NCs) shall be defined in the plan.The ITP shall further contain a column for inspection codes,(e.g. inspection, witnessing and hold points) indicating theinvolvement of Contractor, Purchaser and any 3rd party. It isgood practice to include a reference to the applicable reportingform or document, and to refer to the specific equipment ortools to be used for verification.

Guidance note:It is recommended that the ITP also contains the relevant manu-facturing steps, in addition to the inspection and testing activities,all in the consecutive order they occur during production. Such adocument is sometimes referred to as a ‘manufacturing andinspection plan’ (MIP).


5.3.3 Unless otherwise agreed (see 1.3.4), methods and fre-quency of inspection and testing, as well as acceptance criteriashall be in accordance with the applicable ‘data sheet’ in

DET NORSKE VERITAS


ANNEX 1 or ANNEX 2 of this document. The following notesapply to all ‘data sheets’:

— “according to MPS / ITP” means that testing method and/or acceptance criteria are optional to Contractor but shallbe defined in the MPS / ITP

— “to be included” under “frequency / qualification” meansthat testing shall be included during PQT

— “to be agreed” means that testing shall be carried out, andthat test method and/or acceptance criteria (as applicable)are subject to agreement. (A tentative test method andacceptance criterion is preferably to be specified by Pur-chaser in inquiry and the agreed method / criterion shall beincluded in the contract)

— “by agreement” and “agreed” testing method or accept-ance criterion means that Purchaser may require testing,and/or that methods and acceptance criteria are subject toagreement (to be specified by Purchaser in inquiry andconfirmed in contract).

For specification of amendments and deviations to the ‘datasheets’, see 1.3.6.

5.3.4 The MPS, ITP, and ‘daily log’ shall be in English unlessotherwise agreed.

5.3.5 Procedures and work instructions referenced in the ITPshall be available to all persons concerned with the associatedcoating work and in their normal language.

5.3.6 Purchaser shall have the right to inspect any activityassociated with coating work. Purchaser shall identify any holdpoints for witnessing (see 5.8.2) in the ITP and inform Con-tractor accordingly.

5.4 Coating and blasting materials

5.4.1 In this subsection “coating materials” may refer to mate-rials associoated with FJC, CFR and/or infill.

5.4.2 The selection of coating materials, and the specificationof properties to be verified during qualification and produc-tion, shall take into account the maximum and minimum oper-ating temperature of the pipeline, and any special conditionsduring installation.

Guidance note:Unless included in Contractor’s scope of work, the selection ofgeneric types of coating materials (e.g. high density PE or PP)shall be specified by Purchaser. (This selection is typically car-ried out during conceptual design).


5.4.3 Supplier specific coating materials shall be specified byContractor in the MPS. Purchaser may specify in inquiry anypreferences for supplier specific coating materials.

Guidance note:Prior to the issue of a specific purchase order, Purchaser or Con-tractor may choose to qualify specific coating material formula-tions according to their own requirements for FJC / CFR (whichneed not be project specific). Such coating qualification shouldbe specific to a production facility, and a defined range of pro-duction process parameters. Purchaser or Contractor may requirewitnessing of the coating material qualification testing, either byhimself or by a third party, or that the qualification testing shallbe performed by a third party.


5.4.4 Coating and ‘infill’ materials shall be described by sup-plier in specific ‘product data sheets’ (PDS), including relevantproperties of raw materials and processed “as applied” materi-als, recommendations for surface preparation, application tem-perature range, conditions for curing or drying, as well asdetailed instruction for storage and handling. The PDSs shall

be included in the MPS.

5.4.5 Testing and certification of coating material propertiesmay either relate to properties of raw materials (i.e. “as deliv-ered”), or to properties of processed materials i.e. “as applied”.In the latter case, test panels with applied coating, or speciallyprepared coating layers (i.e. without substrate) are used.

5.4.6 Certain properties related to raw materials “as deliv-ered” for coating shall be certified per batch or lot (i.e by an“inspection certificate” - type 3.1.B according to EN 10204 orISO 10474), in accordance with section 2, column “Produc-tion”, of the ‘data sheet’ in ANNEX 1 and ANNEX 2. Contrac-tor may specify further properties for batchwise certification asindicated ”by agreement” in the data sheet (to be included inpurchase document).

Guidance note:In the case of continuous production, “batches” will not applyand a “lot” is defined, based e.g. on hours or on weight and/orvolume of production.


5.4.7 For properties of processed “as applied” coating materi-als, and in particular those related to long-term environmentaldegradation resistance, data for a representative productspecification (i.e. not batch or lot specific) will normally applyand a “test report” based on non-specific testing is issued (e.g.EN 10204, Type 2.2 or ISO 10474). For certain coating sys-tems, mandatory requirements for certification of such proper-ties (not batch or lot specific) apply as indicated by “to beincluded” or “to be agreed” in section 2 of the ‘data sheet’, col-umn “coating material qualification”, see 1.3.2. Contractormay specify further properties for certification as indicated ”byagreement” in the ‘data sheet’ (to be included in purchasedocument, see 1.3.4). The specified physical properties in thedata sheets should be regarded as indicative. Other values maybe agreed based on project specific requirements.

5.4.8 Properties of blasting materials shall be documented(e.g. in a product data sheet for inclusion in the MPS).Abrasives for stainless steel linepipe shall be based on fusedaluminium oxide, stainless steel shot or non-ferrous garnetaccording to an appropriate standard.

5.4.9 Contractor shall verify that all coating materials andabrasives received are in accordance with the specifiedrequirements in the MPS. The verification may include actualtesting by Contractor (or by a third party), and/or a review ofmanufacturer’s certificates. Review of certificates and any ver-ification testing to be performed by Contractor shall beincluded in the ITP.

5.4.10 Until compliance with specified requirements has beenconfirmed, the coating and blasting materials received byContractor shall be kept physically separated from checkedmaterials. Any materials checked and found non-conformingshall be clearly marked and quarantined.

5.4.11 All materials to be used for surface preparation andcoating shall be contained in their original packing until useand shall be adequately marked, including:

— manufacturer’s name and location of manufacture— material type/designation— batch/lot number— weight (for materials in drums, bags or similar)— size (for materials in rolls or similar)— date of manufacturing (and shelf life, if applicable)— manufacturing standard (if applicable)— short instruction for storage and handling (including

health and safety notes).

5.4.12 Contractor shall ensure that all materials for coatingand surface preparation are stored and handled so as to avoiddamage by the environment or other effects. Supplier’s recom-mendations for storage and use shall be readily available forPurchaser’s review.

5.4.13 All completed FJCs / CFRs and ‘infills’ shall be trace-able to individual batches or lots of coating materials.

5.5 Initial inspection of linepipe coating and of field joints to be coated

5.5.1 Inspection of linepipe coating (if included in the scopeof work) and assessment of coating damage for CFR shall becarried out as specified by Purchaser (see 1.3.3). Such inspec-tion may include visual examination and/or “holiday” detec-tion (manual or automatic). A detailed procedure shall then beincluded in the MPS.

Guidance note:Characterisation of damage to the linepipe coating should distin-guish between e.g.

a) superficial defects that can be repaired by light surfacedressing

b) defects with major reduction in coating thickness but with-out exposure of bare metal (or no indication by “holiday”detector)

c) damage that extends down to the pipe material or an innercoating layer (indication by holiday detector).


5.5.2 Dimensions of parent coating cutback, chamfer geome-try and general conditions of the parent coating in the overlaparea shall be inspected as required to confirm suitability for thespecific FJC system.

5.5.3 The girth weld and adjacent steel surface to be coatedshall be subject to an initial visual examination. Any organiccontaminants like oil and grease shall be removed by usingsuitable solvents or detergents (type to be specified in MPS).Dirt or salts shall be removed by high pressure washing withfresh water. Any dents, laps, weld sputter or other surfacedefects that could deteriorate the properties of the coating shallbe eliminated by light grinding (“cosmetic”) only. Purchasershall be informed if any defects cannot be removed by suchmeasures.

Guidance note:Cleaning of pipe ends from dirt and salts should be carried out bythe welding contactor prior to welding. Removal of weld sputterand any other surface contaminants associated with the weldingprocess should also be included in welding contractor’s scope ofwork. However, Contactor shall confirm that the surface is suit-able for FJC and carry out corrective measures if required.


5.6 Preparation of steel surface and linepipe coating overlap for application of coating

5.6.1 All surface preparation and associated inspection andmonitoring activities shall be carried out according to the qual-ified MPS (5.1) and the ITP (5.3.2).

5.6.4 The blasting material and pressurised air system shall bekept dry and free from injurious contaminants, including salts,oil and grease. Recycled blasting material shall be checked forcleanliness at regular intervals (to be specified in the ITP andrecorded in the ‘daily log’). Checking of oil contaminationshall be carried out according to ASTM D4285. Conditioningof grit during production shall be described in the MPS.Special precautions shall be taken to avoid contamination ofblasting materials for stainless steel linepipe (to be specified inMPS).

5.6.5 For stainless steel pipes, abrasives shall be based onfused aluminium oxide, stainless steel shot or non-ferrous gar-net according to an appropriate standard. Any brushing orgrinding shall be carried out using stainless steel tools only.Precautions shall be taken to avoid contamination by e.g. resid-ual C-steel particles, C-steel tools and handling equipment.

5.6.6 The pipe surface shall be at least 3°C above the dewpoint temperature and the ambient relative humidity notexceed 85% during the blast cleaning. Pre-heating is requiredif the humidity is higher.

5.6.7 Dust or abrasive remains shall be removed from the pipesurface using dry clean air, vacuum cleaning, brushing or anequivalent technique. Compressed air quality shall be control-led (to be specified in MPS / ITP). Surface cleanliness androughness shall be verified as detailed in the applicable FJC /CFR ‘data sheet’ in ANNEX 1. Measurements of residual saltcontamination may be performed using special proprietaryequipment if specified in the ITP, and provided that compli-ance with the referenced standard can be demonstrated.Prepared field joints not meeting specified requirements shallbe subject to new surface treatment. In case of failure duringfractional testing of surface treatment, the testing frequencyshall be increased until the efficiency of corrective actions hasbeen confirmed.

Guidance note:If salt contamination is established during production testing,measures should be taken to remove such contamination prior towelding using washing by high-pressure fresh water.


5.6.8 Precautions shall be taken to avoid rusting and/or con-tamination after completed surface preparation. The affectedareas shall be efficiently shielded from atmospheric precipita-tion, sea spray, etc. Requirements to maximum durationbetween blasting and coating, and/or maximum relativehumidity shall be specified in the MPS / ITP.

5.6.9 Cleaning of the parent coating overlap area is normallyrequired to remove any contamination or thermal degradationof the coating surface by steel surface preparation or previoushandling. Such cleaning and any further mechanical prepara-tion of parent coating cutback for FJC / CFR shall be specifiedin MPS / ITP.

5.7 Coating application

5.7.1 All work associated with coating application shall becarried out according to the qualified MPS (see 5.1 and 5.2).Purchaser may specify that coating applicators shall be quali-fied individually during the PQT (5.1.2). The manning of theapplication crew, including any supervisor, shall not be lessthan during the PQT, except for any activities that will notapply during production. Once the MPS has been qualified,

any changes shall be formally accepted by Purchaser througha ‘concession request’ (CR).

5.7.2 Coating application temperature, any pre-heating ofcoating materials, and drying or curing conditions shall com-ply with coating material suppliers’s recommendations (see5.4.3) and/or the qualified MPS.

5.7.3 Parent coating shall be shielded from any detrimentaleffects of preheating of steel surface and coating application.Direct heating of steel surface after completed surface prepa-ration, if applicable, shall be by induction heating. The appliedfrequency shall be such that adequate through-thickness-heat-ing is achieved. The control of heating shall ensure that anyaccidental heating of the pipe wall to a temperature higher than270°C is prevented. Flux shields may be required to preventexcessive heating of parent coating by induction heating. Anydirect heating of PE / PP parent coating overlap shall be by hotair or infrared heat. Pre-heating by gas torches is not allowed,except for FJC/CFR systems 1A and 1B.

5.7.4 Adequate shelter from rain and wind shall be provided.Throughout coating application, essential parameters affectingthe quality of the coating (e.g. steel temperature and relativehumidity, pre-mixing of ‘infill’ components) shall be moni-tored and recordings noted in the ‘daily log’ (5.8.8). Equip-ment for monitoring (e.g. temperature and pressure sensors,injection flow meters.) shall be calibrated at scheduled inter-vals as specified in the ITP (5.3.3).

5.7.5 Control of coating application parameters shall be suffi-cient to verify that individual layers of coating are appliedwithin the qualified temperature range and time frame for theapplication of individual layers, in order to achieve the speci-fied coating thickness, inter-layer adhesion and other proper-ties of each layer.

Guidance note:For more complex FJC systems, this will normally require use ofautomatic control of heating and coating application.


5.7.6 The design of any permanent moulds or straps for ‘infill’shall be accepted by Purchaser.

5.8 Inspection and testing of coating

5.8.1 Completed FJC / CFR and ‘infills’ shall be inspectedand tested according to the ITP (5.3.2). Any changes shall beformally accepted by Purchaser through a ‘concession request’(CR).

Guidance note:Inspection of FJC / CFR (including any ‘infill’) is to a largeextent based on visual inspection. It is essential that acceptancecriteria are defined in quantitative and objective terms as far aspractical, based on results from the PQT and/or previous experi-ence. Photographic documentation of acceptable contra non-acceptable defects may be helpful.


5.8.2 Purchaser shall be allowed to witness all inspection and/or testing. For any special hold points identified by Purchaser(see 5.3.6), Contractor shall give adequate notice for Purchaserto arrange for witnessing. Purchaser may further specify thateach FJC / CFR shall be formally accepted by an inspector ofhis choice.

Guidance note:Purchaser should consider the needs and benefits of carrying outquality surveillance during production, either as single audits orcontinuous presence by trained and qualified inspectors.


5.8.3 Inspection and testing of coated pipes during qualifica-tion and production shall be carried out according to the appli-cable methods, acceptance criteria and frequencies specified inthe applicable FJC / CFR and/or infill data sheet, and anyamendments made in purchase documents (see 1.3.4). If alter-native test methods are given in the data sheet and Purchaserhas not specified any preference in purchase document (see1.3.5), then the selection of method is optional to Contractor.

5.8.4 Purchaser may specify testing of specific coating prop-erties by destructive testing during production. Such testingmay then be carried out on a dummy pipe piece or on an actualfield joint to be stripped and recoated (or possibly repaired ifaccepted by Purchaser) after testing.

5.8.5 Failures during testing which are obviously due todefective sampling or operational errors of testing equipmentmay be disregarded and testing repeated on the same FJC / CFR.

5.8.6 Individual FJCs / CFRs and ‘infills’ not meeting speci-fied criteria shall be recoated, or if possible, repaired accordingto an accepted procedure (see 5.9).

5.8.7 In case of repeated failures to meet specified require-ments, production shall be discontinued. Contractor shall thencarry out an examination of the cause(s) of the failure and issuea ‘non-conformance report’.

5.8.8 All data from inspection and testing of FJCs / CFRs and‘infills’, major repairs and stripping of FJC, recordings ofessential operating parameters, calibration of testing and mon-itoring equipment and time of completed application shall benoted in the ‘daily log’.
